目的：本研究探讨北京市急诊科胸痛患者急诊溶栓及行PCI的情况。方法本研究属多中心前瞻性描述性研究，参研单位包括17所医院。使用统一表格记录入选患者的一般资料，包括既往病史，发病时间，到达医院急诊时间，胸痛特点，心电图描述及诊断，初步诊断，急诊的诊治情况，辅助检查，确定诊断和去向，就诊30d后的临床转归情况。所有数据经SAS8.2统计软件进行统计学处理。结果自2009年7月~2009年8月，在17个医疗中心连续有效入选至急诊室就诊的胸痛患者，计划纳入6000例，最终有5666名患者获得有效记录而入选。男性2663例，占47%，女性3003例，占52%。胸痛患者占各中心日急诊总量的4.65%(3.02%~29.4%)。冠心病患者急诊 CAG 检查：STEMI 急诊 CAG 比例25.8%，NSTEMI 急诊CAG比例4.3%，心绞痛急诊CAG比例0.9%。冠心病患者急诊溶栓治疗：STEMI急诊溶栓比例4例2.6%， NSTEMI急诊溶栓1例1.1%，心绞痛急诊溶栓1例0.1%。急诊胸痛收住院比例12.3%。30 d随访结果：院外死亡37例（0.7%），再次入院275例（4.9%）。结论本研究中溶栓及急诊行CAG及进一步行PCI比率低，患者预后及再入院比例增加，提示目前急诊溶栓及PCI治疗形式仍然很严峻。“,”Objectives To analyze thrombolysis and coronary angiography of patients with chest pain in emergency room. Methods The prospective and across-sectional survey was conducted on patients with chest pain and chest pain equivalent syndrome in 17 medical centers in Beijing in between July to August 2009. Data was collected and processed with SAS8.2 software. Results A total of 5,666 patients participated in the study with age of 58.09±18.39 of which included 2,663 males and 3,303 females. In the coronary heart disease (CHD) patients with CAG examination, CAG in STEMI was 25.8% , CAG in NSTEMI was 4.3% , angina, and CAG proportion was 0.9% . Emergency thrombolysis in patients with coronary artery disease: 4 cases of STEMI emergency thrombolysis (2.6%), 1 case of NSTEMI emergency thrombolysis (1.1%), 1 case of angina (0.1%). 30-day emergency chest pain follow-up result: 37 death cases occurred outside of hospital (0.7% ) and 275 re-hospitalized cases (4.9%). Conclusions Thrombolysis and CAG and PCI ratio reflected low and a higher ratio of re-hospitalization which suggest current emergency thrombolysis and PCI therapy need to be improved.
